PURPOSE:To obtain a lead storage battery which has superior recovering ability after being left discharged by being provided with a negative plate having greater capacity than a positive electrode and making the ratio of theoretical discharge capacity of a positive plate against that of electrolyte to be less than one. CONSTITUTION:The battery is provided with a positive electrode and a negative plate which has greater capacity than the positive electrode, and the ratio of theoretical discharge capacity of the positive plate against that of electrolyte is made less than one. Thus, even if a battery being left discharged, the positive plate comes under every low atmosphere of electrolyte. Hence, since inactive PbSO4 increases dissolving ability and charging current is prevented from decreasing due to passivation during the constant-voltage charging, charging performance can be enhanced. |
